Yes, my road bike but I did take my mountain bike too. The only bad thing was the PT ran out of time and could only fit me to my road bike. Good thing is, I really was not having trouble with the mountain bike I just brought it along to see if it needed adjustment. I'm always lowering and raising the seat on it any way so I don't think it matters as much on a mountain bike. On a road bike you are always pedaling. That constant motion for 4 or 5 hours can irritate a joint that is slightly out of alignment.
